一、教材分析本节内容既是本章教学中的重点也是遗传学教学中的难点,由于减数分裂是三大遗传定律发生的细胞学基础,因此,熟练掌握减数分裂过程是学好遗传和变异的关键。二、学情分析虽然减数分裂过程要比有丝分裂过程复杂,但仍有规律可循,学生只要对照图片比较两者的变化过程进行反复揣摩,大部分学生是可以形成自己对减数分裂过程的认识的。三、教学设想 First, the textbook analysis This section is not only the focus of teaching in this chapter is also a difficult point in genetics teaching, as meiosis is the cytological basis of the three major genetic laws occurred, therefore, proficiency in meiosis process is a good genetic and mutation The essential. Second, the academic analysis Although the process of meiosis than the process of mitosis complicated, but there are still rules to follow, students simply compare the two pictures of the process of comparing the changes to try to figure out, most students can form their own meiosis process Know Third, teaching ideas
